Abstract
Catalytic trimerisation of diisocyanate containing at least80 wt.% 2,4- and/or 2,6- diisocyanatotoluene (TDI) to give an isocyanurate containing below 0.1 wt.% monomeric diisocyanate is effected at 55-120degreesC in the absence of aliphatic hydroxy groups and urethane groups, with the reaction being ended optionally by poisoning the catalyst. Solvent and/or diluent- and isocyanurate group-containing polyisocyanates based on 2,4- and/or 2,6-diisocyanatotoluene (TDI) and with a monomeric diisocyanate content below 0.1 wt.% are obtained by catalytically trimerizing a mixture of diisocyanate (20-80 wt.%) containing at least80 wt.% 2,4- and/or 2,6-TDI; solvent and/or diluent (20-80 wt.%; and a dialkylaminomethyl group-containing phenolic catalysta at 55-120degreesC in the absence of aliphatic hydroxy groups and urethane groups and ending reaction optionally by poisoning the catalyst.
